Blue Dragon's appearance physically is that of a very powerful and intimidating nature with his ripped arms and huge chest muscles, as well as the massive wings on his back. Like most other shadows, the dragon has a aesthetic accesory on its body, this one being gold rings around the horns.
Shu is the first one to get back his shadow after Nene takes it. In fact, he may already have had a shadow before the Flying Fortress event. This is because he seems to have his instantly back just after Nene takes it.
It is the only shadow in the game to fully mimic its masters movements once he wins the battle.
The shadow has strangely different amounts of SP earned compared to others, even with the use of a Black Belt he seems to have a much higher rank than others by a considerable margin of 20 ranks if the player has a high level party.
The Shadow's corporeal form has him gain legs with two front toes and a back toe and a spiked tail, as well as green eyes. In this form, following Shu's movements as he normally does slashing at the enemy with two blades of energy from its claws forming a giant X in the ground. It then shoots a fireball at the center of the X causing massive damage to the opponent.
In Blue Dragon Plus, Blue Dragon's only class is the Magic Sword class, and its corporeal attack, exclusive to Shu (or an attack similar to it) named after the shadow itself like the other shadows, Blue Dragon, causes blue fire in the shape of itself to rise up then rain down blue and orange fireballs.
In Blue Dragon: Awakened Shadow it appears for a short while in the beginning but then Shu loses the ability to use it just the other characters who orginally had a shadow. A new version of this shadow controlled by the player and every other previous player character assigned to it appears in this game too. This one's horns were straighter, had bracelets around its hands, and lacked the spades on its back compared to the original.
AnimeEditShadow (originally a powerful dragon transformed into a shadow by a spell) that was admired, feared, and even worshipped as the embodiment of destruction, striking fear into both friend and foe alike. It is revealed by Killer Bat that he is a direct descendant of the first Darkness, and so he possesses power far greater than any mere shadow.
At the start of the anime Blue Dragon appears when Shu wants to protect his village from falling debris, but Shu is unable to control him. Blue Dragon is very violent, and is extremely cold, not caring about others but himself. At first he did not cooperate with Shu until their fight with Ivanov and Gustav when Shu managed to gain enough power to control him. He prefers not to take orders, but when given the personal chance for freedom he chose to stick with Shu, saying that he liked fighting alongside him. He was sealed away at the end of the first season to defeat the Demon Zola and stop the Darkness from spreading.
In the second season, Blue Dragon is reawakened by a being named Noi to save Bouquet from a red dragon named Mikhael. After learning the truth behind Mikhael's appearance, and after uncovering a plot by the Legion of Elite Species (a council of dragons which both Mikhael and Noi are members of) to eradicate the humans, Blue Dragon assists Shu and the others in saving humanity. Throughout the series, Blue Dragon is given the ability to temporarily merge with various characters in order to battle stronger opponents. He first merges with Bouquet and Hippo, giving him legs, and equipping him with plated armor, as well as a weapon on his right arm which doubles as both a sword and a blaster. He is later given the opportunity to merge with Noi, granting him taloned legs and heavy armorments on his head, chest, and forearms. In this form he also sees an increase in both speed and agility. Finally towards the season's end, after it is revealed by Noi that Shu and Blue Dragon must become one in order to defeat the Legion of Elite Species, the two successfully merge, assuming Blue Dragons "True Form". This new-found power allows Blue Dragon to defeat the Legion of Elite Species with the energy from Shu and the others, and the series ends with Blue Dragon remaining with Shu.

True Dragon FormEdit
After Noi grants Shu the ability to combine with Blue Dragon, he gains a full dragon form without any kind of armor on him. He has three horns in his head, four appendages in neck area and two appendages under his jaws and horn like appendages from neck to tail and a spike at the tip of his tail. Because he has grown legs he has talons to inflict powerful kicks. He can now fire a blue flame of powerful blast from his mouth which is so lethal that it not just overpowered Fagino's flame blast, but also completely destroyed him. It is shown that he can use his tail in close combat to thrash his enemy. He has retained his ability to convert his claws into two blue swords made out of energy in both hands. When he concentrated his power on his fists creating blue lights on them, he was easily able to destroy the clones of Rudolph without any trouble.
Also he can engulf his fists with blue energy to do a blaster punch and when given enough power can release the energy to do a kind of blue flare cannon strike attack which is Blue Dragon's most powerful attack to be known. It is to be noted that when he releases his energy in his true form, the sky and the surrounding will turn blue though it was shown only once when Blue Dragon was summoned by Shu when Noi awakened him. Also it might be possible that Blue Dragon may able to create a forcefield around him just like the Investiture Beings.
His unique ability is that he can enter overdrive when a huge surge of power is generated by Shu causing Blue Dragon to push his limits and obtain a tremendous amount of power that boosts all of his abilities to extreme levels giving him the name known as Heavenly Dragon. This ability is activated when Shu wants to protect someone when he doesn't have enough power. The mechanism behind overdrive is combination between light and darkness which in Blue Dragon's case is combined power of Shu's will to protect others and Blue Dragon's courage to take on any powerful foe. When Shu becomes weak Blue Dragon's body absorbes him due to which they become immobile and Blue Dragons body turns black.
Also it was shown in the end that Blue Dragon can now summon himself at will without Shu's help.
